"Loop" not available in Ride the Lightning

Completely new to running a lightning node and running on Ride the Lightning.

My Ride the Lightning app doesn’t have “loop” as an option on the menu on the left hand side. When I watch tutorial videos they all have this option. I think I have the most updated version of RTL but must not? How do I verify that and where do I download the version that will allow me to loop?

Thanks in advance!!

Same Issue. Would love the answer.

Posted in Github. No longer included. Use loop on Lightning Terminal.
